After the spectacular end of the third round, the fourth round started immediately. There were only 60 of the best participants left and fifty of them will be going home after this round. For the fifth and the final round only 10 participants would be left to compete for the championship.
What the participants needed to do in the fourth round was easy. They needed to show how well they were able to mana itself. Mana control was one of the most important abilities that a mage needed to have and in this case that would be the main ability which would be put to test. That would not be the only ability though, other things like mana sense and magic design would also be tested.
